BOTTLE-STOPPER.

SPECIFICATION forming part of Letters Patent No, 709,162, dated September 16, 1902.. Application filed January 29,1902. SeriallNo. 91,737. (No model.)

To @ZZ whom it 11i/ay concern.-

Be it known that I, IGNATZ KOSCHERAK, a citizen of the United States, residing in New York, borough of Richmond, and State of New York, have invented certain new and useful Improvements in Bottle-Stoppers, of which the following is a specification.

This invention relates to an improved bottle-stopper of that class which is known as the Lightning bottle-stopper, in which a porcelain head isemployed. The porcelain heads hitherto used were objectionable, for the reason that the rubber gasket which is applied to the shank of the head frequently becomes injured and detached while in use; also, the lower end of the head or knob, as the same is technically called, becomes chipped or otherwise injured, and, lastly, that portions of the beverage contained in the bottle become settled at the point of connection of the rubber gasket with the shank, which when not very carefully cleaned imparts a bad taste to the beverage when the bottle is used again.

The object of the present invention is to overcome these disadvantages and to furnish a head or knob for bottle-Stoppers by which the gasket is rigidly secured in position, the lower end of the stopper effectively protected against injury, and any sediment of impure matter at the point of connection between the rubber gasket and head prevented; and for this purpose the invention consists of ahead or knob for bottle-Stoppers in which the lower end of the head is provided with a covering layer or cap of aluminium or other suitable sheet metal, the outwardly-daring edge of which is tightlypressed on the lower end of the gasket, so that the same is firmly retained in position on the head or knob.

In the accompanying drawings, Figure 1 is a side elevation of a bottle with my improved head or knob in position thereon. Fig. 2 is a side elevation of the head or knob drawn on` a larger scale. Fig. 3 is a vertical central section of the same on line 3 3, Fig. l; and Fig. 4 is a detail of the sheet-metal coveringcap used for retaining the gasket in position on the head or knob.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A represents the porcelain head or knob of my improved bottle-stopper. The head is made with the usual shank a and shouldered lower end b. The gasket B is applied to the shank ct and retained on the same at its lower end by a sheet-metal layer or cap C, preferably of aluminium, said cap corresponding in general shape to the shouldered lower end b. The cap C is drawn inwardly, so as to fit tightly over the shoulder, and is provided at its edge with a flaring rim c, as shown clearly in Fig. 1I. The sheet-metal retaining layer or cap C is placed over the shouldered lower end h of the head A and pressed by suitable mechanism over the rubber gasket or packing B, so that the flaring rim of the cap binds on the gasket and retains the same firmly in position, as shown in Fig. 3, so as to prevent the gasket from becoming detached from the shank a, but is permanently retained thereon. At the same time a tight closing of the connection between the aring edge of the sheetlnetal cap and the rubber gasket is produced, so that no impurities can settle at the joint. The cap also forms an effective protection of the shouldered lower end of the head against chipping or other injury to which the same is exposed while in use, so that the head lasts much longer than heretofore and presents a better appearance,owing to the non-tarnishing quality of the aluminium.

Having thus described my invention, I claim as new and desire to secure by Letters Patent-- l. In a bottle-stopper, a porcelain head or knob, the shank of which is provided with an elastic gasket, and a metallic covering-cap applied to the lower shouldered end of the head or knob, said cap having a rim tightly secured against the lower portion of the gasket, substantially as set forth.

2. In a bottle-stopper, a porcelain head or knob, provided with a rubber gasket, and a sheet-metal covering-cap at the shouldered lower end of the head, said covering-cap being provided with an outwardly-flaring rim fitting tightly around the gasket, so as to retain the same firmly in position on the head, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.
